[ProgSoc] mmap

[Nicholas FitzRoy-Dale <wzdd@nospam.tig.com.au>]

Hi :)

I was wondering if anyone knew the specifics of the behaviour of mmap()
under Linux and Solaris. Basically, what's the best strategy to mmap
portions of a file under Linux/Solaris? Assuming a file may be larger
than available memory and the whole file needs to be accessed
sequentially, is it more efficient to mmap portions (say, 1MB large) of
it sequentially, or simply give up on mmap and use read?

Or is there no significant difference?

Any comments appreciated,
